Description

Technical Field

[0001] This utility model relates to the field of gas turbine room data monitoring, and in particular to a gas turbine room wind speed circulation system data monitoring device. Background Technology

[0002] As an important energy conversion device, the gas turbine room's operating efficiency and stability are directly related to energy production and supply. The wind speed circulation system, as an important component of the gas turbine room, ensures smooth air circulation and effective heat dissipation inside the gas turbine room by regulating the wind speed, thereby ensuring the normal operation of the equipment. At the same time, the wind speed circulation system can also improve energy utilization efficiency and reduce energy consumption and emissions.

[0003] In traditional gas turbine room wind speed circulation systems, the installation and maintenance of data monitoring devices, especially speedometers, present numerous inconveniences. First, speedometers are typically installed using bolts and nuts for fixing. This method not only requires special tools for installation and disassembly but also takes a long time, increasing installation costs and potentially delaying system deployment and commissioning. In practical applications, this cumbersome installation method often leads to low work efficiency, hindering rapid system deployment and flexible adjustments.

[0004] Secondly, as a key component for monitoring wind speed, the speedometer usually needs to be inserted into the pipeline to work. However, due to the complex environment inside the pipeline and the high wind speed, dust and dirt easily accumulate on the surface of the speedometer's sensor. These accumulations not only affect the sensor's performance and lead to inaccurate measurement data, but may also damage the sensor and shorten its service life.

[0005] Therefore, it is necessary to provide a new data monitoring device for the gas turbine room wind speed circulation system to solve the above-mentioned technical problems. Utility Model Content

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0037] Please see Figures 1 to 7A data monitoring device for a gas turbine room airflow circulation system includes: a pipe 1, a speedometer 3, a mounting block 4, a snap-fit ​​assembly, a cleaning brush 5, a drive block 6, and a transmission mechanism. One end of the pipe 1 is connected to a fan, and the other end is connected to the gas turbine room. A support frame 2 is installed at the bottom of the pipe 1. The speedometer 3 is installed inside the pipe 1, and the mounting block 4 is installed at the top of the pipe 1. The mounting block 4 has a through hole communicating with the pipe 1. A snap-fit ​​assembly is installed between the speedometer 3 and the mounting block 4 to quickly install the speedometer 3 inside the pipe 1. A cleaning brush 5 is located on the side of the pipe 1 near the speedometer 3, and a drive block 6 is located on the side of the cleaning brush 5. A transmission mechanism is installed between the pipe 1 and the drive block 6 to drive the gas turbine room. The drive block 6 drives the cleaning brush 5 to clean the dust at the bottom of the speedometer 3. The snap-fit ​​assembly includes: a positioning ring 7, a spring 8, a snap-fit ​​block 9, and a snap-fit ​​groove 10. The mounting block 4 has symmetrical square grooves inside. Springs 8 are fixedly connected to the inner walls of the two square grooves. Snap-fit ​​blocks 9 are fixedly connected to one end of each of the two springs 8. The outer walls of the two snap-fit ​​blocks 9 are slidably connected to the inner walls of the corresponding square grooves. The positioning ring 7 is fixedly connected to the middle of the speedometer 3. Snap-fit ​​grooves 10 corresponding to the two snap-fit ​​blocks 9 are opened on both sides of the speedometer 3 near the positioning ring 7. The two snap-fit ​​blocks 9 snap into the corresponding snap-fit ​​grooves 10. A sealing cover 11 covering the through hole is rotatably connected to the bottom of the mounting block 4. A torsion spring 8 is installed between the mounting block 4 and the sealing cover 11. A sealing ring 12 matching the sealing cover 11 is fixedly connected to the bottom of the mounting block 4.

[0038] It should be noted that: airflow is generated by the fan, and the airflow is sent into the gas turbine room through pipe 1 and finally discharged from the gas turbine room, forming a wind speed circulation. The speed measuring instrument 3 monitors the wind speed in real time and transmits the data to the control system. The control system adjusts the fan speed according to the data to maintain the wind speed in the turbine room within the set range.

[0039] The bottom of the speed measuring instrument 3 is equipped with a probe with a sensor to monitor the wind speed change in the pipe 1. Before the speed measuring instrument 3 is installed, the sealing cover 11 at the bottom of the mounting block 4 is closed under the action of the torsion spring 8 to prevent air leakage in the pipe 1 and affect the detection quality.

[0040] Please see Figure 5 , Figure 6 and Figure 7The transmission mechanism includes: a motor 13, a transmission rod 14, a driving bevel gear 15, and a driven bevel gear 16. The motor 13 is fixedly connected to the top of the support frame 2. The output end of the motor 13 is fixedly connected to the transmission rod 14. One end of the transmission rod 14 is fixedly connected to the driving bevel gear 15. Two fixed rings are symmetrically fixedly connected inside the pipe 1. The driven bevel gear 16 is rotatably connected to the inner wall of one of the two fixed rings. The driving bevel gear 15 and the driven bevel gear 16 are meshed. A reciprocating screw 17 is fixedly connected to one end of the driven bevel gear 16. The end of the reciprocating screw 17 away from the driven bevel gear 16 is rotatably connected to the inner wall of the other of the two fixed rings. A slider 18 is fitted onto the middle of the reciprocating screw 17. The top end of the slider 18 is fixedly connected to the drive block 6. A limiting block 19 is fixedly connected to the bottom of pipe 8, a limiting groove 20 is fixedly connected to the inner wall of pipe 1, the limiting block 19 is slidably connected to the inner wall of the limiting groove 20, a cylinder 21 is symmetrically fixedly connected to the inner wall of pipe 1 near the speed measuring instrument 3, a tension spring 22 is fixedly connected to the inner wall of each of the two cylinders 21, a sliding rod 23 is fixedly connected to the top of each of the two tension springs 22, the two sliding rods 23 are slidably connected to the inner wall of the corresponding cylinder 21, the top of each sliding rod 23 is fixedly connected to one end of the cleaning brush 5, an extension rod is fixedly connected to the outer side of the cleaning brush 5, a roller 24 is rotatably connected to the bottom end of the extension rod, soft bristles are provided on the inner side of the cleaning brush 5, the two ends of the drive block 6 are designed with bevels, the outer side of the cleaning brush 5 is designed with bevels, and anti-slip texture is provided in the middle of the speed measuring instrument 3;

[0041] It should be noted that the limiting block 19 at the bottom of the slider 18 is installed in conjunction with the limiting groove 20 on the inner wall of the pipe 1, so that when the reciprocating screw 17 rotates, the slider 18 can move smoothly along the limiting groove 20. The slider 18 reciprocates on the reciprocating screw 17 for one stroke, which can drive the cleaning brush 5 to clean the probe at the bottom of the speed measuring instrument 3 twice.

[0042] The bottom of the cleaning brush 5 is connected to the roller 24 via an extension rod, which greatly reduces the friction when the drive block 6 contacts the roller 24. This makes it easier for the slide bar 23 at the bottom of the cleaning brush 5 to move up and down inside the cylinder 21. The design of the tension spring 22 at the bottom of the slide bar 23 makes the cleaning brush 5 descend more smoothly and reduces the impact of wind resistance. The design of the reciprocating screw 17 parallel to the wind direction and the inclined surface design on one side of the cleaning brush 5 can also reduce wind resistance to a certain extent.

[0043] The working principle of the data monitoring device for the gas turbine room air velocity circulation system provided by this utility model is as follows:

[0044] One end of the fan is connected to the air source through pipe 1, and the other end is connected to the gas turbine room through pipe 1. After the fan is started, it generates airflow and sends the air into the gas turbine room through pipe 1 to achieve air circulation.

[0045] Installation process:

[0046] The operator holds the anti-slip textured area in the middle of the speed measuring device 3 to ensure a firm grip. They align the slot 10 in the middle of the speed measuring device 3 with the locking block 9 inside the mounting block 4 to ensure smooth insertion. The bottom of the speed measuring device 3 is slowly inserted into the through hole inside the mounting block 4. During insertion, the outer wall of the speed measuring device 3 presses against the locking block 9, compressing the spring 8. Simultaneously, the bottom of the speed measuring device 3 pushes the sealing cover 11 open. The speed measuring device 3 is then inserted until the positioning ring 7 contacts the mounting block 4. At this point, the spring 8 inside the mounting block 4 releases its elasticity, pushing the locking block 9 to engage with the slot 10 inside the speed measuring device 3, completing the installation.

[0047] After the speed measuring instrument 3 is installed, it begins to monitor the airflow speed inside the pipe 1 in real time. When the airflow passes through the pipe 1, the speed measuring instrument 3 can accurately capture the airflow speed data and transmit it to the corresponding data monitoring system. The data monitoring system receives and processes the data transmitted by the speed measuring instrument 3 and makes a judgment based on the preset threshold. If the airflow speed is abnormal or exceeds the preset range, the system will issue an alarm and take corresponding measures to ensure the normal operation of the gas turbine room airflow circulation system.

[0048] Disassembly process:

[0049] The staff member grips the anti-slip textured area in the middle of the speed measuring instrument 3 again to ensure a firm grip, and pulls the speed measuring instrument 3 upwards. This causes the slot 10 inside the speed measuring instrument 3 to press against the locking block 9 inside the mounting block 4 and compress the spring 8. The staff member continues to pull the speed measuring instrument 3 until it is completely pulled out of the pipe 1. At this time, the sealing cover 11 at the bottom of the mounting block 4 automatically rebounds under the action of the torsion spring 8, maintaining contact with the sealing ring 12 to prevent air leakage.

[0050] Cleaning process:

[0051] When motor 13 is started, it begins to run. Motor 13 drives the driving bevel gear 15 to rotate via transmission rod 14. The driving bevel gear 15 meshes with the driven bevel gear 16, causing the driven bevel gear 16 and its reciprocating screw 17, which is fixed at one end, to rotate. The slider 18, which is fitted into the middle of the reciprocating screw 17, begins to move, thereby moving the drive block 6 fixedly connected to its top. During the movement of the slider 18, the limiting block 19 fixedly connected to its bottom moves within the limiting groove 20 fixedly connected to the inner wall of the cylinder 21, ensuring that the slider 18 can move stably. When the slider 18 reaches the bottom of the speed measuring instrument 3... When the inclined surface of one end of the drive block 6 contacts the roller 24 at the bottom of the cleaning brush 5, the slider 18 continues to move, causing the cleaning brush 5 to be squeezed upward and move to clean the probe at the bottom of the speed measuring instrument 3. When the cleaning brush 5 moves upward, the slide rod 23 fixedly connected at both ends moves upward inside the cylinder 21 and stretches the tension spring 22. When the cleaning brush 5 moves to the highest point (that is, the roller 24 at the bottom of the cleaning brush 5 is at the top of the drive block 6), as the slider 18 continues to move, the inclined surface inside the other end of the drive block 6 begins to contact the roller 24. Under the action of the tension spring 22, the cleaning brush 5 begins to move downward and return to its original position.

[0052] When the slider 18 moves to one end of the reciprocating screw 17, it begins to move in the opposite direction, and the same process occurs again, driving the cleaning brush 5 to clean the probe at the bottom of the speedometer 3 again.

[0053] After cleaning is complete, slider 18 continues to move in the opposite direction, returning to its initial position, ready for the next cleaning operation.

[0054] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
